SAFETY LOCK.

Application filed December 15, 1921, serial No. 522,553. Renewed. May 9, 1925.

T 0 all whom it may concern:

Be it known that I, SALVADOR ANGIRA GARCIA, a citizen of Mexico, and a iesident of Guadalajara, in the State of Jalisco, Mexico, have invented certain new and useful Improvements in Safety Locks, of which the following is a specification.

My invention is an improvement in safety locks, and has "for its object to provide a device of the character specified, adapted for securing containers otevery character, in such manner that any attempt to gain access to the contents of the container will be indicated by the state of the look.

In the drawings:

Figure 1 is a plan view of one embodiment of the lock in use,

Figure 2 is a section on the line 2-2 of Figure 1,

Figures 3 and 4c are views similar to Figure 2 showing modified constructions.

In Figures 1 and 2 the embodiment is shown in connection with container 1 of usual construction. having a sealing flap 2 by means of which the contents of the container may be enclosed. The improved lock consists of sections 3 and 1, one of which is secured to the sealing flap and the other to the body of the envelope.

The section 8 is a plate having at one end a flange or web 5 which is bent to lie approximately parallel to the body of the plate, and at the opposite end has laterally extend ing pointed spurs or lugs 6. The flange is in eflect a hook, and this hook is adapted to engage a similar hook on the other section.

The plate lie of doubled formation. consisting of the body and a portion 7 extending approximately parallel with the body, and this portion 7 has at its free end a hook or flange 8 similar to the hook 5 and adapted to engage the same. The body portion of the plate 4 has laterally extending pointed spurs or lugs 9 similar to the lugs 6 for a like purpose. and it will be noticed referring to Figure 2 that the hook 8 is between the lugs at that end of the section.

The two portions of the section t diverge slightly from each other toward their free ends, and the hook 5 of the section 3 may be inserted between these portions to permit it to be engaged with the hook 8. When so engaged it will be obvious from an inspection of Figure 2 that the engagement is hidden and concealed.

tune, the spurs 6 and 9 are pressed through the material of the container, when such container is an envelope or box, and then bent parallel with the bodies of the section to secure the section to the container. It the container is of metal, wood or the like, the sections may be secured directly to the material in any suitable or desired manner.

In Figure 3 the fastener consists of sections 10 and 11, the section 10 having a hook 12 corresponding to the hook 5, and laterally extending spurs or lugs 13. The hook 12 however is turned in the opposite direction to the hook That is, the hook 12 is on the opposite side 01 the section from the spurs or lugs, while the hook 5 is on the same side.

The section 11 is a doubled strip of metal formed in the same manner as the section l, but the upper portion is provided with a book 13 tor engagement by the hook 12 instead of the lower portion, as in Figure 2. In this arrangement the section 11 has a spur or lug 14: at the end remote from the section 12 which is struck up from the material of the strip.

In Figure 41- the sections 15 and 16 have the spurs or lugs 17, and the engagement between the sections is by means of a tongue 18 struck up from the lower portion of the section 16 and a slot 19 formed in the section 15.

The section 16 is of double formation like the sections 4 and 11, and the tongue 18 is struck up from the lower portion as before stated. Normally this tongue lies against the upper portion of the section, and when the section 15 is inserted between the double portions of the section 16 the tongue is forced downward, and when the slot 19 is reached the tongue springs upward, and a slight withdrawal of the section tightly locks them together, the tongue passing through the slot.

It will be obvious that any form of the invention might be connected with the ends of a cord, for instance, for connecting said cord about a container, as for instance a packet of letters. The improved lock sections are connected merely by pressing them together, far enough in Figures 2 and 3 so that the hooks will engage, and far enough in Figure 4: so that the tongue 18 will engage p the slot 19. p p

In order to unlock or loosen the fastener, it is necessary to destroy the same; The spurs or prevent the lateral movement of the sections with res Ject to each other, so that engagement and isengageinent must be direct and in the line of the length of the axis of the lock as a whole I claim i 1. A lock of the character described, comprising two sections, one of which comprises two plies, the outer ends of which are into grally connected and the inner ends free and adapted to receive the opposing end of the other section therebetween, and one of the plies of the two-plysection having its inner end terminating in an inwardly turned hook and the opposing end of the other section terminating in a similar inturned hook whereby the same may be engaged with the hook upon the two-ply section when slid inwardly andbetween saidplies and securing tangs extending from each section, the tangs of the two-ply section extending from the uppermost ply, whereby to clamp the plies of this section upon each other and thereby insure against the sections becoming disengaged from each other.

2. A look of the character described, comprising two sections, each made of thin spring metal, and one of said sections com prising two plies, the outer ends of which are integrally connected andthe inner ends adapted to receive the opposing end of the other section therebetween, a hook formed upon the free end of the lowermost ply of the two-ply section and extending inwardly and adapted to abut against thebottom surface of the uppermost ply, a similar hook formed upon the opposing end of the other section and disposed upon the similar face of said section and adaptedto be extended between the plies of the two-ply section and engage with the hook of the lowermost ply whereby ,to secure said sections together and securing tangs extending from each of said sections, the tangs upon the two-ply section extending from the uppermost ply, whereby to enable the upper ply to be held compressedand thereby insure against disengagement of the sections from each other.
